Question1

A football lineman charges an opponent with a force of 175lbs in direction of 310 degrees. The opponent charges back with a force of 185 lbs in the direction of 90 degrees. What is resultant force, and in what direction will it react?

Question2

A standard 0.505 1 inch diameter tensile specimen has 2.0 inch Gage length. The load corresponding to the 0.2 percent offset is 15000 lb and the utmost load is 18500 lb. Fracture occurs at 16200 lb. diameter after fracture is 0.315 inch and the gage length at fracture is 2.53 inch. Analyse the standard properties of the material from the tension test.
